usd_relbbox

Since	18.0

vector  usd_relbbox(<stage>stage, string primpath, string purpose, vector position)

Returns the relative position of the given point with respect to the bounding box of the primitive.

<stage>

When running in the context of a node (such as a wrangle LOP), this argument can be an integer representing the input number (starting at 0) to read the stage from. The integer is equivalent to the string form referencing a particular input, e.g., “opinput:0”.

You can also use this argument to refer to a USD file (e.g., “/path/to/file.usd”), or to another LOP node’s cooked stage using the op: as the path prefix (e.g., “op:/stage/lop_node”).

primpath

The path to the primitive.

purpose

The primitive’s purpose for which to use the bounding box (e.g., “render”).

Returns

The relative position of the given point with respect to the bounding box of the primitive.

// Get the points relative position.
vector pt = {1, 0, 0};
vector rel_pt = usd_relbbox(0, "/src/sphere", "render", pt);
